IMPROVEMENT INSPINDLES FOR SPINNING-MACHINES.v

Specification forming part of Letters Patent No. 212,725, dated February25, 1879,' application filed November 20, 1ere.

To all whom it may comme:

Be it known that I, JOSEPH A. MILLER, ofV the city and county ofProvidence, State of chines; and I hereby declare that the followthe artto make and use the same, reference.` being had to' the accompanyingdrawings forming part of this specification.

The object of this invention is to so construct a spindle forspinning-machines that the faster 1 it revolves and the more it isloaded withn yarn the steadier it will run.

The invention consists in the combination, with a spindle, spindle-step,or equivalent means for supporting a whirl, of a spool or bobbincarrier, and means by which rotative motion is imparted to the spindle,spool, or bobbin carrier, while the same is free to adjust itself toitsown center of magnitude or the center of gravity and revolve around thesame unaffected by the pull of the band or other means by which rotationis imparted to the same.

All spindles for spinning-machines may be divided into two parts, commonto all. The first is that portion of the spindle supported in the stepand bolster, to which the whirl or equivalent is secured, and by whichit is rotated. The second is that portion of the spindle to which thebobbin, the spool, or cop-tube spindles are, therefore, driven by samemotive force, and they drive the cop-tubo, spool, or bobbin on which theyarn is spun; and the two portions of the spindles heretofore made wererigidly secured together, no matter how much they differed in theirdetails of construction. In all spindles where a whirl is used to rotatethe spindle, the pull of the band acts as a disturbing force, no matterhow elastic or yielding the bolster or free the step. To relieve thespindle and cop, spool, or bobbin from the effect of this disturbing'element, and allow them to balance themselves on their true central axesat high speed, is the object of this invention.

In the drawings, Figure l is a view of one form of my improved spindleprovided with a bobbin. Fig. 2 is a sectional view, showing thespindle-step with its whirl, the ball and socket connecting thebobbin-carrier with the whirl, and the stop or shield by whieh'the ballis prevented from rising and the lateral motion thereof limited, so asto prevent the bobbin from coming in contact with the spinning-` ring. Aproblematic position of a spindle 'with a spool is shown in brokenlines. Such a spool would describe a spiral line at its upper part untilthe true center of gravity was reached, when it would runon its truecentral Aaxis as long as the speed was maintained, such as is now usedfor spinning. Fig. 3 is a sectional view of a anged disk for thereception and retention of the lower end of the bobbin, and the lowerend of the spindle connected with the whirl by a universal joint, whichallows thebobbin to adj ustitself to its true center.

Fig. 4L shows the cap or guard secured to the whirl, and rotating withthe same, as also an elastic packing, by which the spindle is held to,or nearly to, its true axis, but free to yield and adjust itselfaccurately to the same.

When the bobbins or spools are light and of small diameter, or when theyarn is wound on a cop-tube or the bare spindle, a disk, similar to thebobbin-holder shown in Fig. 3, rmly secured to the spindle, may be used.

In the drawings similar letters of reference indicate correspondingparts in all the figures.

a represents a spindle-step having a bearing in a suitable bolster. b isa whirl, to the upper part of which a socket, c, is iixed, arranged toreceive a ball, and provided with two or more slits, in which the pinssecured to the ball loosely fit. d is the ball secured to the spindle e,and provided with two or more pins radiating from the center of the balland titting loosely in the slits of the cup c. The spindle c isconnected withy the step a, so as to rotate with the same, but mayrotate at an angle from the axis of the step a.. h represents thebobbin.

While it is desirable that the spindle e and bobbin h shall be free torotate on their true axes instead of their mechanical axes, it isnecessary to prevent the bobbin or spindle from comin g in contact withthe ring and traveler. The guard f is therefore placed around thespindle, and a tube, the top thereof being larger than the spindle,limits the angle to which the spindle can lean out of the perpendicularaxis of the step a. The guard is secured to the bolster-rail, and alsoprevents the ball d from rising out of the cup c.

In Fig. 4, the guard f is secured to the Whirl, and an elastic packing,g, is placed between the spindle and the guard, so that the spindle isheld at or near its mechanical axis, but is free to adjust itself to thetrue axis of the spindle, bobbin, and the load.

The guard and whirl shown in Fig. 4 rotate together with the step andspindle.

l, Fig. 3, is a circular disk, with a project ing conical ilange, intowhich the bobbin may be secured by frictional contact, or it may be heldby pins. The disk l acts as a balance- Wheel, being secured to thespindle, and may be used in a modified form when the bobbin is securedin any other manner.

In place of the ball-and-sockct joint any other connection may be usedthat imparts rotation to the spindle and leaves it free to find its truecenter. The device shown in Fig.

. 4 may be used without the pins, and the spindle may be driven by thefrictional contact of the elastic material gon the spindle by screwingthe guard f down sufficient to secure proper frictional contact. Whileat the usual high speed of from five to ten thousand turns the spindleand its load will be sufficiently free to find their center of gravityand run true.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. rEhe combination, with a spindle-step and Whirl,of a spindle connected with the spindlestep by means of aball-and-socket joint, as and for the purpose described.

2. The combination7 With a driven spindle, of a spindle step or supportconnected with the driven spindle by an elastic or yielding joint,whereby the axes of the spindle-step and driven spindle are brought inline solely by the rotary movement of said parts, substantially as setforth.

3. The combination, with the spindle a, Whirl b, and cup c, providedwith slits, of the spindle c and ball d, provided with pins,substantially as and for the purpose set forth.

4. rIhe combination, with the whirl b, cup c, spindle e, and ball d,ofthe guard f and elastic packing g.
